Caraudio crossover for PA speakers?

[Joe89 10+ year member]

I know this will not be the correct way to do things, however...

I would like to listen to my Eminence Beta's and ST350's before I install them in my vehicle.

I have some passive crossovers for Memphis PR 6.5" component speakers.

I am aware that crossover points are impedance dependent, but given that the Memphis 6.5" speakers are 4ohm, and I can wire (2) Beta's in parallel to 4ohm, (same case for the Memphis tweeters and ST350's), will I be okay testing the speakers (with low wattage) in this manner? In my vehicle the speakers will be run with an active crossover.

Edit: Just realized the receiver I am using to power these is only stable at 8ohm. Anyone have any ideas? Can a set of useable crossovers be found at Radioshack or Fry's for cheap?

Edit2: I suppose I will turn this into an educational project and attempt to build my own passive xo's. http://www.parts-express.com/resources/building-a-crossover.cfm I will be following this guide. Now, I have to see if I can source the necessary capacitors, inductors, resistors, etc locally...

ideas:

The drivers themselves may be 8 ohms but you also have to account for the resistance of the crossover. Without getting into a lengthy post, you'll likely be fine for a short test. If you want to turn them into your new home theater speakers, that's different.

do realize passive crossovers have a wattage limit. also! you can use pa equiptment in car enviroments and car audio and live enviroments. its just not always recommended.
